Acton brush fire burns 126 acres; blaze 40% contained

Officials earlier said the fire had burned about 40 acres, but the size was revised after an aerial survey was conducted, the Los Angeles County Fire Department said.

Firefighters were dousing hot spots and cutting lines around the perimeter of the blaze, which destroyed at least one structure and threatened homes as winds picked up Tuesday afternoon.

"We'll be working through the night to get the hot spots and make sure it doesn't start back up," Inspector Quvondo Johnson told The Times.

He said an aggressive air attack, which included five helicopters and fixed-wing aircraft, helped crews on the ground gain the upper hand. At the fire's height, nearly 400 firefighters were battling the blaze.

The blaze broke out shortly before 4 p.m. near the 4700 block of West Crown Valley Road in the Soledad Canyon area.

The cause was under investigation. The blaze burned medium to heavy brush.
